Clarence "Gatemouth" Brown (April 18, 1924 — September 10, 2005) was a Louisiana and Texan American musician. He is best known for his work as a blues musician, but embraced other styles of music, having "spent his career fighting purism by synthesizing old blues, country, jazz, Cajun music and R&B styles" (New York Times obituary).
He was an acclaimed multi-instrumentalist, who played an array of musical instruments such as guitar, fiddle, mandolin, viola as well as harmonica and drums. He won a Grammy Award for Best Traditional Blues Album in 1982 for his album, ''Alright Again!''
